|
|
<p><small>GDB</small> internally maintains a number of output streams: the console, the
|
|
target, and the log. The output intended for each of these streams is
|
|
funneled through the <small>GDB/MI</small> interface using <em>stream records</em>.
|
|
</p>
|
|
<p>Each stream record begins with a unique <em>prefix character</em> which
|
|
identifies its stream (see <a href="GDB_002fMI-Output-Syntax.html#GDB_002fMI-Output-Syntax"><small>GDB/MI</small> Output
|
|
Syntax</a>). In addition to the prefix, each stream record contains a
|
|
<code><var>string-output</var></code>. This is either raw text (with an implicit new
|
|
line) or a quoted C string (which does not contain an implicit newline).
|
|
</p>
|
|
<dl compact="compact">
|
|
<dt><code>"~" <var>string-output</var></code></dt>
|
|
<dd><p>The console output stream contains text that should be displayed in the
|
|
CLI console window. It contains the textual responses to CLI commands.
|
|
</p>
|
|
</dd>
|
|
<dt><code>"@" <var>string-output</var></code></dt>
|
|
<dd><p>The target output stream contains any textual output from the running
|
|
target. This is only present when GDB’s event loop is truly
|
|
asynchronous, which is currently only the case for remote targets.
|
|
</p>
|
|
</dd>
|
|
<dt><code>"&" <var>string-output</var></code></dt>
|
|
<dd><p>The log stream contains debugging messages being produced by <small>GDB</small>’s
|
|
internals.
